Question

Water flows through a horizontal pipe that branches into two identical pipes, each with cross-sectional area equal to $ \tfrac{1}{2} $ the cross-sectional area of the original pipe. How does the speed of the water in one of the smaller pipes compare to the speed in the original pipe?(a) The speed is $ 4 $ times greater in the smaller pipes.
, (b) The speed is $ \tfrac{1}{2} $ of that in the original pipe.
, (c) The speed is $ 2 $ times greater in the smaller pipes.
, (d) The speed is the same as in the original pipe.
